iOS 8打印交互控制器在iPad上的高度为0

我试图提供一个UIPrintInteractionController实例，以使用AirPrint打印图像。起初似乎什么都没有发生，但在委托方法

printInteractionControllerdPresentPrinterOptions:

中，我使用

self.presentedViewController

获取有关假定的“presented”打印交互控制器的信息。原来它的宽度是19.000，高度是0.000。。。在viewcontroller实际呈现之前，似乎没有办法访问它，因为它在框架中都是自动生成的，而且我还无法成功修改它的帧后呈现。其他人是否遇到此问题和/或找到解决方法

- (void)printBadgeImage:(UIImage *)image {

    UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];

    UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = BADGE_PRINT_JOB;
    printInfo.duplex = UIPrintInfoDuplexLongEdge;
    pic.printInfo = printInfo;
    pic.printingItem = image;
    pic.delegate = self;

    UIPrintInteractionCompletionHandler completionHandler =
    ^(UIPrintInteractionController *printController,
      BOOL completed,
      NSError *error) {

        if (completed) {

            NSLog(@"Print job completed");

        } else if (!completed && error) {

            NSLog(@"Print job error");
            NSString *errorString = [NSString stringWithFormat:@"An error occured while printing: %@", error];
            UIAlertView *alert = [[DOSimpleAlertView alloc] initWithTitle:@"Error"
                                                                  message:errorString];

            [alert show];

        } else {

           NSLog(@"Print job incomplete without error");
        }
    };

    [pic presentFromRect:self.view.frame
                  inView:self.view
                animated:YES
       completionHandler:completionHandler];

}

我有一个可以打印图像的应用程序，但是我已经很久没有看代码了。但是这里是简介，希望能有所帮助

NSData *moneyData = UIImageJPEGRepresentation(image, 1.0);
UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
if(pic && [UIPrintInteractionController canPrintData: moneyData] ) {

    pic.delegate = self;

    UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = @"MONEY";
    printInfo.duplex = UIPrintInfoDuplexLongEdge;
    pic.printInfo = printInfo;
    pic.showsPageRange = YES;
    pic.printingItem = moneyData;

    [pic presentFromBarButtonItem:self.printButton animated:YES completionHandler:nil];
}

如果我没记错的话，你展示它的方式有些特别。你可能想试试我的按钮
